At STABL Energy, we are building modular battery systems that rethink how energy storage is deployed and scaled. Our cloud platform connects, monitors, and operates these systems in the field - forming the digital backbone of our products.
Your Role
As Team Lead, you take end-to-end ownership of STABL's Battery Cloud - the platform that connects our fleet of battery systems, processes real-time telemetry, and enables operational excellence through internal tools and customer-facing services.
You will lead a small but highly capable team (currently 2 engineers) and remain technically hands-on. This is a startup leadership role: you set direction, make architectural decisions, and contribute directly to implementation.
You operate at the intersection of IoT, distributed systems, and product engineering - bridging embedded edge devices, AWS infrastructure, and user-facing applications.
Your mission
You are accountable for the architecture, reliability, and scalability of our cloud platform.
This includes:
- Defining and evolving the overall cloud architecture (IoT connectivity, data ingestion, storage, APIs, portal)
- Ensuring reliable and secure connectivity of our BESS fleet in the field
- Designing scalable telemetry pipelines and time-series data infrastructure
- Owning observability, uptime, and operational robustness
- Leading the development of our internal service and operational tools
- Establishing engineering standards for cloud development, deployment, and cost efficiency
- Hiring, mentoring, and structuring the Cloud team as we grow
- Aligning technical decisions with product, firmware, service, and compliance stakeholders
- Proven experience leading engineering teams in a startup or fast-moving product environment
- Strong background in designing and operating distributed systems in AWS cloud environments
- Experience with IoT architectures and device connectivity at scale
- Solid understanding of data pipelines, time-series storage, and API design
- Hands-on proficiency in modern backend development using TypeScript and Python
- Experience with infrastructure as code using CDKTF
- Ability to switch between strategic thinking and hands-on implementation
- Strong communication skills and ability to work across firmware, hardware, operations, and compliance teams
- Experience in energy systems or industrial IoT is a strong plus.
